     DETAILED DESCRIPTION OF THE INVENTION 
     Having reference to the drawings, attention is directed to FIG. 1 which illustrates a grab handle secured in its operative embodiment on a motor vehicle, with the grab handle being generally identified by the numeral 10. The motor vehicle 12 to which the grab handle in FIG. 1 is secured is a truck, more specifically a pick-up truck. 
     The motor vehicle 12 has a conventional light system 14 including head lights 15 positioned along its front 16 and auxiliary lights 17 which typically function both as parking or running lights as well as turn signal indicators, with these lights being secured along the side 18 of vehicle 12. Also shown is door 20 having a door handle 22. 
     As can be seen in FIGS. 1, 2 and 3, the grab handle 10 of this invention comprises a vertically extending gripping portion 25 preferably fabricated from steel, and having a generally circular cross-section. Grab handle 10 also comprises means for attaching the gripping portion 25 to the side of the vehicle. Preferably this attachment means 27 is a bracket as can be seen in drawings. The attachment means 27 is secured to the side 18 of the vehicle 12 by fastening means 30, preferably screws or bolts, however, the bracket could be welded to the vehicle. The vertically extending gripping portion 25 has ends 32 and 33 located at the opposite ends of the gripping portion. Associated with the ends 32 and 33 are lamp portions 35 and 36 respectively. Lamp portions 35 and 36 in turn each contain light bulbs 37 and 38 respectively. The light bulb used with this invention includes a first filament 39 as well as a second filament 40, with the light bulbs 37 and 38 being secured into first and second sockets 41 and 42 respectively. The sockets are shielded from water and dirt by caps 44 and 45 which provide a seal with respect to ends 32 and 33. The cap could be fabricated from metal or be made of a suitable plastic material. 
     As can best be seen in FIG. 3, an insert member 50 is positioned between each cap and the tubular component of the vertically extending gripping portion 25. The insert 50 is secured to the vertically extending gripping portion by suitable means, including adhesive or welding. This insert member 50 has a threaded portion 52 along at least part of its outer wall 53. Meanwhile, the caps 44 and 45 both comprise a threaded inner wall 55 thereby permitting mechanical inter-engagement between the insert and cap. Also shown is the electrical circuitry associated with the running light 56 and the electrical circuitry associated with the turn signal 57. The running light electrical circuitry 56 provides current to the first filament 39, while the turning signal electrical circuitry 57 provides power to the second filament 40 associated with both light bulbs 37 and 38. 
     FIG. 4 shows a modified embodiment of the invention for use in an alternatively constructed truck 58. The modified handle 60 is configured similarly to the side of the vehicle so as to be oriented approximately parallel thereto. However, as opposed to the preferred embodiment of the invention wherein the handle is straight, this handle can be seen as being slightly curved. FIG. 4 also shows a modified means for attaching the handle to the truck in the form of a modified bracket. This modified bracket 62 includes fastening portion 64, positioned adjacent the side of the truck 58, a gripping portion engaging portion 66 which is in contacting engagement with the vertically extending gripping portion of the modified handle 60, and a slanted connecting portion 68 which is intermediate the fastening portion 64 and the gripping portion engaging portion 66. As can be seen, one of the slanted connecting portions 68 slants upwardly between the fastening portion and engaging portion, while the other slants downwardly between the same respective components. 
     In actual operation, the grab handle serves a plurality of functions. In addition to providing a grab handle to assist in the entrance to or exit from a vehicle, the illumination of the first filament of the lights can serve as an indicator for the location of the grab handle to assist in embarking or disembarking at night. Additionally, when the engine is running and the vehicle is in motion, the first filament serves as a means to warn traffic or pedestrians of the presence of the vehicle, since the grab handle serves as an additional running lamp. Further, the second filament of the grab handle permits the lights to serve as additional turn signal indicators. 
     From the above description it will be seen that a multi-purpose grab handle is provided The invention assists in providing additional safety for the driver of a motor vehicle, in addition to assisting in the safety of pedestrians and other drivers.
